NavBarControl.PaintStyleKind Property
Gets or sets the kind of the NavBarControl’s paint style.
Namespace: DevExpress.XtraNavBar
Assembly: DevExpress.XtraNavBar.v18.2.dll
Declaration
Property Value
| Type | Default | Description |
|---|---|---|
| NavBarViewKind | **Default** | A NavBarViewKind enumeration member which specifies the kind of the NavBarControl’s paint style. |
Available values:
| Name | Description |
|---|---|
| Default | The nav bar is painted using the currently applied WindowsXP theme or Skin. |
| ExplorerBar | The nav bar is painted flat, using the currently applied WindowsXP theme or Skin. |
| SideBar | The nav bar is painted like a Side Bar, it can only be painted flat, using the Style3D style or the currently applied WindowsXP theme. |
| NavigationPane | The nav bar is painted like a Navigation Pane, the look and feel settings are ignored. |
Remarks
Don’t confuse the PaintStyleKind property with the NavBarControl.PaintStyleName property. The NavBarControl.PaintStyleName property specifies the paint style used to paint the nav bar and this overrides all the look and feel settings specified by the NavBarControl’s NavBarControl.LookAndFeel property. The PaintStyleKind property specifies only the manner - kind, in which the nav bar is painted and allows the look and feel settings to be applied.
There are three kinds of paint styles: ExplorerBar, SideBar and NavigationPane. The ExplorerBar kind allows the nav bar to be painted flat, using the currently applied WindowsXP theme or Skin. If the nav bar is painted like a Side Bar, it can only be painted flat, using the Style3D style or WindowsXP theme currently applied. If it’s painted like a Navigation Pane, the look and feel settings are ignored.
Example
This example shows how to create a NavBarControl in code.The NavBarControl will have two groups ('Charts' and 'Settings') with items. Item link selection is enabled by setting the LinkSelectionMode property to LinkSelectionModeType.OneInGroupAndAllowAutoSelect. To respond to a link selection, the SelectedLinkChanged event is handled. In the OneInGroupAndAllowAutoSelect mode, each group can have a single selected link independent of other groups. When a group is activated and it has no selected link, the first link is auto-selected. At runtime, you will see that the SelectedLinkChanged event fires on group activation, while the LinkClicked event does not. The example demonstrates two methods of assigning images to navbar items:1) explicit assignment of Image objects to items (see the 'Charts' navbar group item initialization);2) implicit assignment, using image indexes (see the 'Settings' navbar group item initialization).
